From what I understand, gut and eurosonics are way big compared to steel. I really dig my spirocores (med. tension). I just get worn out though when I start slapping several songs during a gig. I was wondering if any of the nylons out there were of similar diameter to spirocores, 'cause I know I'll eventually want to go back to them. I don't want to be recutting the nut or shaving the bridge, etc. Will I just have to live with the pain?
